Thanks for all, good forum, always good tips. I think the leakage is between the plastic "tank" and aluminium cell. Not repairable? After 280 000 km and 18 years perhaps time to buy a new one.


New radiator will be the type with built in cooler, which is more efficient,than the extension cooler, so I found, car ran 5-10.c cooler with the inbuilt cooler.
Yes, it came with built in version (Denmark Quality), but perhaps not a must to modify piping to use that, or what do you recommend?

Fit it in place of the leaking one along with the original oil cooler :y

You may have to swap the clips/bracket fastenings from the old radiator but it will all fit as the original  :y

The plastic plugs on the oil cooler fittings on the new radiator can be left in place in order to keep moisture/dirt out ;)

The metal pipes can simply be disconnected and tied back to the coolant bottle. As you lift the radiator etc out, undo the two screws attaching the condenser and leave it in the location. Once out, you can undo the four screws attaching the oil cooler to the radiator... Keep it upright and you won't lose a significant amount of transmission fluid  :y

...started finally to remove radiator. Does this above mean that I can remove the oil cooler pipes by unscrewing the Torx bolt above the oil cooler or do I have to remove the metal pipes from rubber hoses? Otherwise seems to be quite simple so far.

It's easier to remove the 2 clips from the bottom of the cooler metal pipes pipes, and put something in the pipes to stop leakage,

So I mean is it a risk to try to open bolt No. 3 after 20 years. Removing rubber pipes seems for me more complicated and might put some dirt into oil circulation, too?

undo the hoses as BG suggested; easier and less problematic. Wipe them clean first but you do that with every joint, don't you? ;)

All I ever did was undo #3 and lift #1 up and back and tie it to the header tank to hold it out of the way ;)

Keep the three radiators upright as you separate them and you won't lose any ATF. no point over complicating it.

Thanks DG, thats what I, However, decided to do, too.

1. Parts '2' O-rings are no more available, if not reusable does anyone know dimensions of them.
2. I have three fans; two in front of condenser and the third behind radiator. I took this third one "up" with radiator. Could that have been left there down?
3. Looking at pics the rubber hose seems to be a bit "wet" in both ends. Is this normal looking, I have two options if not. Renew the rubber pipe or change the oil cooling to the built in cooler in new Nissens radiator. Then have to do some piping work, do you think worth doing?




I have three fans

I changed to the built in cooler, would run about 5'c cooler too, I think you need the pipes from a built in cooler car thou. Been a while.

he would need the radiator fittings, plus some suitable hose and clamps to join to his existing pipes. The fittings will be a standard metric thread......

I remove the bagpipes and rear fan before pulling the radiator... gives you a bit more wiggle room.

Not had an issue with O ring reuse.

Replace the hose, but be mindful that the aluminium pipe is fragile. Personally I would refit it as is.

Thanks for all comments, difficult to make decisions? What I really think would be best solution is to buy this pc No. 3. I guess it fits to my old rubber hoses. Any good source for this?

Opel if they still do it, but you have more chance of obtaining a new oil cooler for your car...
